DANGER
During the installation of the CX plus, there is a risk of electric shock. For this reason, installation,
commissioning and maintenance may exclusively be performed by a skilled electrician with the
necessary qualification. A skilled electrician is a person who has the ability, experience and
knowledge necessary for the construction, installation and operation of electrical equipment and
systems and who is trained in the detection and prevention of potential hazards.
During installation, the relevant regulations for the installation of switchgear and for the prevention
of accidents must be observed and complied with. Devices with damaged or open housing or
terminals may not be connected to the mains and must be disconnected immediately.
The current transformer must be short-circuited prior to disconnecting the current measurement
path at the device resp. at the current transformer. Otherwise, there may be a life-threatening
voltage at the connections of the current measurement path resp. of the transformer. In the long
run, the transformer will be destroyed by the high voltage.
